NUT-LOOK.

To all whom, it may concern:

Be it known that I, J OI-IN B. YOUNG, a citizen of the United States,residing atIios Angeles, in the county of Los Angeles and State ofCalifornia, have inventednew and useful Improvements in Nut-Locks, ofwhich the following isa specification.

The present invention relates to loeknuts, and resides in theconstruction, combination and arrangement of parts set forth in thefollowing description and falling within the scope of the appendedclaims.

In the drawing: Figure 1 is a view of a lock nut constructed inaccordance with my invention and showing the same in applied position ona bolt, Fig. 2 is a sectional view illustrating the arrangement of thelocking member of the nut co-acting with the threads of the bolt, andFig. 8 is a similar sectional view but illustrating the locking elementbrought out of engagement with the threads of the bolt to permit of theremoval of the bolt from the nut.

Referring now to the drawing in detail, the numeral 1 designates a boltof any ordinary construction which may have its threaded shank providedwith longitudinal notches, as indicated in Fig. 1.

The numeral 2 indicates a nut of the ordinary construction and which isadapted to have its threaded bore eo-act with the threaded shank of thebolt 1. The nut is provided with a longitudinally extending depressionor channel 3 which enters from one of the faces of the nut andterminates a suitable distance away from the opposite face of the nut.This channel is arranged above the bore of the nut, but the nut isfurther provided with an opening at which enters the said bore of thenut as well as the channel 3. The opening l may be provided by drillingthe nut at a right angle to its channel 3 and a filler member or blockinserted in the portion of the opening above the channel, as will beclearly understood.

The numeral 5 designates the locking element for the nut. This elementis preferably constructed from a single strand of spring wire, and hasits outer end bent to provide an eye 6 which normally projects throughthe channel 3 to the outer face of the nut. The Wire is coiled toprovide a helical spring 7, the said spring frietionally engaging withthe wall of the channel 3. The opposite end of the body portion of thestrand 5 of the lock is bent upwardly and Specification of lLettersPatent.

Application filed March 7, 1913.

PatentedJune 2, 1914. Seria1iNo752 715L outwardlyat an angle asdesignated by the numeral S,and:is= fronrthence turued clownwardly andat a direct right angle to: the body 5 toprovide'an engaging toothll-which normally extends throughthe opening 4- to within the bore ofthe nut and as a conse' quence into engagement.- with the threads of theshank of the bolt, and to within one of the series of notches providedby the threads. lVhen it is desired to raise the tooth 9 out ofengagement with the threads of the bolt, an inward pressure upon the eye9 will force the lock inwardly so that the tooth 9 will contact with theinner wall of the opening to cause the same to bend and to be entirelyreceived within the said opening However, I have found it desirable toprovide the lower wall of the channel 3 beyond the inner wall of theopening a with an inclined lower portion 10 upon which the strand of theportion 8 rests and which when the memher 5 is forced within the channel3 will guide the tooth 9 upwardly out of the bore of the nut.

From the above description, taken in connection with the accompanyingdrawing, the simplicity of the device, as well as the advantagesthereof, will, it is thought, be perfectly apparent to those skilled inthe art to which such inventions appertain without further detaileddescription.

Having thus described the invention, what I claim is:

1. In a device for the purpose set forth, the combination with a boltand a nut therefor, said nut having a transversely extending channeldisposed away from its bore and being further provided with an openingwhich communicates with the bore of the nut and with the channel, thewall of the channel beyond the opening being inclined toward the end ofsaid channel, a locking element arranged within the channel, saidelement comprising a member which has one of its ends extending throughthe channel and its opposite end bearing against the inclined wall ofthe channel, and being further provided with a teeth which projectsthrough the opening into the bore of the nut and into engagement withthe teeth of the bolt.

2. In a device for the purpose set forth, the combination with a boltand a nut therefor, said nut having a transverse channel which opens atone of its faces and which is disposed away from its bore, the said nutbeing further provided with an opening which communicates with the boreof the nut and with the channel, the wall of the channel adjacent theopening being inclined at an angle to the terminal wall of the channel,a locking member, said locking member being constructed from a strand ofwire having one of its ends bent to provide an eye which projectsthrough the channel, the said member being coiled to provide a helicalspring which frictionally contacts with the wall of the channel, theopposite end of the member being bent upwardly to contact with one ofthe straight walls of the channel and being bent downwardly at an angle,the said angular portion being arranged upon the angular portion of thechannel and terminating in a tooth which projects through the opening ofthe nut into the bore of the nut and into engagement with the threads ofthe bolt.

In testimony whereof I afiix my signature in presence of two witnesses.
